[yocto] GDB problems

I'm trying to run GDB to debug code on my target. Whenever I start
it up, I get this warning:
warning: Unable to find libthread_db matching inferior's thread library, thread debugging will not be available.
and indeed, no thread debug commands will work.
I've found that the library /usr/lib/libthread_db.so is not being
installed in the rootfs. However, just adding this library isn't
enough. The file /lib/libpthread-2.60.so has been stripped on the
target and this also breaks GDB. Installing a non-stripped version
of this library lets GDB do thread debugging.
Both of these libraries come from the eglibc package. How can I
adjust that recipe to:
* Install libthread_db.so
* Avoid stripping libpthread-2.16.so
It looks like the libthread_db.so file(s) should be installed via
the 'eglibc-thread-db' package, but I can't find this package anywhere
on my system.
Any pointers?
Thanks
